  •  QTL Experiment in Brief
    Animals:A half-sib family was developed using one Brahman x Hereford sire. The sire was mated with MARC III (1/4 Hereford, 1/4 Angus, 1/4 Red Poll and 1/4 Pinzgauer) cows in 1996 to produce 259 offspring, of which 126 were males.
     Breeds associated:
    Design:Body weight, scrotal circumference and testicular length in situ were obtained for each bull, using procedures described by Lunstra et al. (1988).
    Analysis:A total of 130 markers were used in the analysis for this study. Amplification reactions were performed with purified DNA extracted from blood with a saturated salt procedure. Amplification conditions have been described elsewhere (Kappes et al. 1997).
